THE WORLD: LAST 24 HOURS

Scientists are not so much interested in the meteorite itself. Rather, they want to see if other objects spotted out on the Meridiani plains are also meteorites and what that might tell them about Mars. If sand is continually blowing in and being deposited on the surface, burying things and building up terrain over time, meteorites will be covered and few will be seen, Squyres said. But if fine surface material is being continuously stripped away by the wind, coarse things like meteorites will be left behind and their accumulation will show. "So whether you're seeing a net accumulation or a net burial of the meteorites is going to tell you something about what the erosion or deposition rates are out on the plains," Squyres said. Opportunity landed Jan. 24 on the Meridiani plains, halfway around the planet from where its twin, Spirit, set down in the Gusev Crater region on Jan. 3, 2004. Opportunity, a six-wheeled robot geologist, quickly discovered rocks showin its area of Meridiani was once soaked in water, the major scientific finding of the twin-rover mission. After that, it explored rocks in a deep crater and then went to conduct an engineering study of its heat shield, which was jettisoned before landing. The meteorite was sitting nearby. "I've actually told the team that we probably shouldn't linger here long because this is obviously the place at Meridiani Planum where large metal objects fall from the sky," Squyres joked. During the weekend, the rover drove to the meteorite and deployed its instrument arm to confirm its composition. Indonesian towns some lost 90% of population
BANDA ACEH, INDONESIA - The United Nations on Wednesday detailed the staggering devastation wrought by South Asia's earthquake-spawned killer waves and called for more aid. UN officials said a clearer picture was emerging of the destruction in Indonesia's Aceh province. In some areas, fatality rates topped 75 per cent and 100 per cent of the homes were destroyed, said Kevin Kennedy, a senior official in the UN Office for the Co-ordination of Humanitarian Affairs, in a briefing at the United Nations. The town of Calang, for example, lost 90 per cent of its population - or 6,550 people out of the pre-tsunami population of 7,300, he said. The survivors are in dire need of assistance, he added. All told, the Dec. 26 tsunami killed more than 162,000 people in 11 nations around the Indian Ocean. Delegates gathered at an international disaster conference in Kobe, Japan, called for a tsunami warning system in the Indian Ocean like the one that already exists in the Pacific.

The international community has pledged billions of dollars in various forms of relief, and the United Nations wants $977 million US from member nations to cover the emergency humanitarian needs of an estimated five million people. So far, $739 million US has been offered, and Annan asked donors to convert their promises into cash as quickly as possible. In Indonesia's Aceh province, which suffered two-thirds of the tsunami deaths, U.S. helicopters were flying 80 missions a day, said Capt. Matt Klunder, Naval Air Wing 2 deputy commander. With the stepped-up flights, villagers were no longer mobbing the helicopters out of desperation as soon as they touched down, he said. "Now there's a little more confidence because they know that on a somewhat regular basis we can get them foodstuffs and water," he said. In the past week, the missions have begun reaching survivors who had sheltered in the mountains after the tsunami and only recently felt safe enough to return to the coast, Klunder said. Among that group, the needs are still great and conditions sometimes desperate, he added. Across the sea in Sri Lanka, where the death toll was expected to exceed 40,000 people, aid efforts were proceeding smoothly and equitably to areas under government and rebel control, Kennedy said. Tamil rebels in the island nation have been fighting for a separate homeland for nearly three decades.-Bert Hernan.
India tests sophisticated surface-to-air short-range missile NEW DELHI, INDIA- India tested its most sophisticated short-range missile on Wednesday, a news agency reported. The surface-to-air missile was test-fired from a range in India's main testing centre in Chandipur-on-Sea in the eastern state of Orissa, Press Trust of India said. With a range of 9.6 kilometres, the solid fuel-propelled missile known as "Trishul" is capable of targeting aircraft and sea-skimming missiles. It can carry a warhead of up to 15 kilograms. Trishul means trident, the weapon favoured by Shiva, the Hindu god of destruction. Wednesday's test firing came as India accused nuclear-armed rival Pakistan of violating a 14-month ceasefire in disputed Kashmir, over which the two have fought two of their three wars since gaining independence from Britain in 1947. Pakistan denied the charge. India and Pakistan routinely test-fire missiles for military use. When they test long-range missiles, India and Pakistan give advance notice to each other. India's missile arsenal includes the short-range ballistic missile Prithvi, the medium-range Agni and Akash missiles, the anti-tank Nag missile and the supersonic Brahmos missile.
